The guitar thing is only apparent to geeky tossers. Worry ye not, "while my guitar gently weeps" was a song written by George for the White Album.

I can only assume that the guitar was found whilst looking for source pics.

The guitar...
... was an intentional selection but I don't think that you need know the relevance of it to understand the picture.
